## Where the full texts are

This page is a summary. Primary license and notice texts are bundled inside
the app and readable with no network:

**Settings → About Crabrix → Open-source licenses → any component.**

They are also in this repository under `Crabrix/Resources/Licenses/`.
The exact primary and vendored toolchain notice archives are also bundled
in the app under Compiler and sysroot dependency notices. The searchable
index includes all 1,592 source packages, including build-time dependencies.
The original archives and their provenance remain public assets of the pinned
toolchain release linked above. Website copies are at https://crabrix.com/licenses/. This summary does not
replace any component's terms.
